DESCRIPTION OF EMBODIMENTS
[0028] The waterproof cover having a cut-off packing which is
squeezed from both sides in the direction of the width of the
above-mentioned mobile electronic device requires the thickness of
the wall which stands the pressure on the cut-off packing, thereby
increasing the dimension in the direction of the width.
[0029] Furthermore, the above-mentioned waterproof cover needs the
space for reservation of the bending R at the four corners of the
cut-off packing.
[0030] In addition, when the waterproof area is, for example, a
battery storage unit, it is difficult to satisfy both the increase
of the dimension in, for example, in the direction of the width of
an electronic device by an increase of the recent battery capacity,
and the maintenance of the dimension of the electronic device for
operability of the electronic device.
[0031] For downsizing a mobile electronic device, the space in
which the cut-off packing is arranged is restricted. Therefore,
when there occurs a displacement of a cut-off packing, the cut-off
function is not maintained.
[0032] The mobile electronic device and the waterproof cover
according to the embodiments of the present invention are described
below with reference to the attached drawings.
[0033] FIG. 1 is an exploded perspective view of a mobile telephone
1.
[0034] FIG. 2 is a perspective view of a cover unit viewed from the

[0038] The body unit 10 includes a plane part 12 provided around
the battery storage unit 11. The plane part 12 is formed on the
same surface continuously along the periphery of the battery
storage unit 11. The plane part 12 is an example of a contact
surface which is formed on the same surface and contacts a sealing
member 23 of the cover unit 20.
[0039] The plane part 12 is formed in the size in which the plane
part 12 may keep contact with the sealing member 23 while the
sealing member 23 is sliding when the cover unit 20 is attached to
the mobile telephone 1 by the sealing member 23 contacting the
plane part 12 and sliding in the pressed state.
[0040] As illustrated in FIGS. 1 through 3, the cover unit 20
includes a cover body 21, a resin sheet 22, a sealing member 23, a
nail unitary construction regulation unit 24, and a wall unitary

and forms the surface of the bottom side in the back of the body
unit 10 (back of the mobile telephone 1). In addition, as
illustrated in FIG. 2, there are a left wall 21a, a right wall 21b,
and a bottom wall 21c around the cover body 21. These left wall
21a, right wall 21b, and bottom wall 21c form a part of the right
and left sides and a part of the bottom of the body unit 10.
[0042] The resin sheet 22 is rectangular thin plate, and is
attached to the inside of the cover body 21 through a double-sided
tape. The resin sheet 22 is made of, for example, polyethylene
terephthalate, polycarbonate, or polyimide, and is flexible.
[0043] The sealing member 23 is provided all along the periphery of
the battery storage unit 11 at the peripheral end part of the
surface (inside the cover unit 20) of the resin sheet 22.
[0044] As illustrated in FIG. 4, the resin sheet 22 may be a resin
sheet 22-1 in frame form formed all along the periphery of the
battery storage unit 11. An inner periphery surface 22-1a of the

12.
[0048] As illustrated in FIGS. 2, 5, and 8, the nail unitary
construction regulation unit 24 includes two nail units 24a and 24b
engaged in the body unit 10, and a coupling unit 24c which is
provided as a unitary construction with the two nail units 24a and
24b, and connects the two nail units 24a and 24b.
[0049] Thus, the nail unitary construction regulation unit 24 is
provided as a unitary construction with the two nail units 24a and
24b and the coupling unit 24c. The nail unitary construction
regulation unit 24 regulates the position of the sealing member 23
by touching the resin sheet 22 on a regulation surface 24d on the
opposite side of the nail units 24a and 24b.
[0050] As illustrated in FIGS. 2 and 5, three wall unitary
construction regulation units 25 are provided each projecting from
the left wall 21a as a unitary construction with the left wall 21a.
The wall from which the wall unitary construction regulation unit
25 projects may be a wall (the right wall 21b, the bottom wall 21c,
etc.) other than the left wall 21a, and a plurality of wall unitary
construction regulation units may project from a plurality of
walls.
[0051] The wall unitary construction regulation unit 25 projects
from the left wall 21a so that an open side end part 25a having a
rectangular section one of whose four sides is open faces the left
wall 21a. In addition, the wall unitary construction regulation
unit 25 regulates the position of the sealing member 23 by touching
the resin sheet 22 at a close side end part 25b on the opposite
side of the open side end part 25a.
[0052] As illustrated in FIG. 6, the wall unitary construction
regulation unit 25 may be a wall unitary construction regulation
unit 25-1 which projects from the left wall 21a so that an open
side end part 25-1a as one side of the H-shaped section faces the
left wall 21a. The wall unitary construction regulation unit 25-1
regulates the position of the sealing member 23 by touching the
resin sheet 22 at another open side end part 25-1b.
[0053] As illustrated in FIG. 7, the wall unitary construction
regulation unit 25 may be a wall unitary construction regulation
unit 25-2 which is a rectangular parallelepiped, and projects from
the left wall 21a so that one end part 25-2a faces the left wall
21a. The wall unitary construction regulation unit 25-2 regulates
the position of the sealing member 23 by touching the resin sheet
22 at another end part 25-2b.
[0054] Furthermore, the wall unitary construction regulation unit
25-2 may be arranged as one or more sets each configured by two
units, or arranged as one or more wall unitary construction
regulation units 25-2.
[0055] As illustrated in FIG. 9, the nail unitary construction
regulation unit 24 may be a nail unitary construction regulation
unit 24-1 in which each (convex part) of two nail units 24-1a (only
one is illustrated) connected by a coupling unit 24-1c projects
from the cover body 21 as having a rectangular section one of whose
four sides is open. The nail unitary construction regulation unit
24-1 regulates the position of the sealing member 23 by touching
the resin sheet 23 at an end part 24-1d on an aperture 24-1e
side.
[0056] As illustrated in FIG. 10, the nail unitary construction
regulation unit 24 may be a nail unitary construction regulation
unit 24-2 in which a nail unit 24-2a (only one unit is illustrated)
and the regulation surface 24d are provided as a unitary
construction for each convex part not connected by a coupling unit.
The nail unitary construction regulation unit 24-2 regulates the
position of the sealing member 23 by projecting from the cover body
21 as having a rectangular section one of whose four sides is open,
and touching the sealing member 23 at an end part 24-2d on an
aperture 24-2e side.
[0057] As illustrated in FIG. 11, the cover unit 20 slides with the
sealing member 23 contacting the plane part 12 in a pressed state
(direction D1 of sliding), and with the nail units 24a and 24b
engaged in the body unit 10, thereby attaching the cover unit 20 to
the mobile telephone 1.
[0058] However, as illustrated in FIG. 12, the cover unit 20 may be
a cover unit 20-1 which does not slide, but is attached to the
mobile telephone 1 by being engaged in the body unit 10 (direction
D2 of engagement).
[0059] As a regulation unit which regulates the position of the
sealing member 23, a wall of the cover body 21, for example, the
left wall 21a and the right wall 21b illustrated in FIG. 17 may
regulates the position of the sealing member 23 by touching the
resin sheet 22.
[0060] In addition, when the resin sheet 22-1 in frame form
illustrated in FIG. 4 as described above is used, a plurality of
regulation units 26 which touch the inner periphery surface 22-1a
of the resin sheet 22-1 may be arranged on the cover unit 20. In
the example in FIG. 18, a regulation unit 26 is arranged as four
units each of the left and right of the cover unit 20, and two
units each in front and at back of the cover unit 20.
[0061] Furthermore, as illustrated in FIG. 19, a plurality of
regulation units 26 which touch the inner periphery surface 22-1a
of the resin sheet 22-1 in frame form, and a plurality of
regulation units 27 which touches an outer periphery surface 22-1b
may be arranged on the cover unit 20. In the example in FIG. 19,
two regulation units 26 are arranged each in front, at back, left,
and right.
[0062] In the three wall unitary construction regulation units 25
illustrated in FIG. 2, for example, the wall unitary construction
regulation unit 25 may be arranged near the corner of the sealing
member 23 (around the front end or the back end in the direction D1
of the sliding as illustrated in FIG. 19), thereby more correctly
regulating the position of the sealing member 23.
[0063] In the present embodiment, the sealing member 23 is arranged
on the cover unit 20 (resin sheet 22) side, but the sealing member
23 may be arranged on the mobile telephone 1 side, and the plane
part (contact surface) 12 may be arranged on the cover unit 20
side.
[0064] Furthermore, in the present embodiment, the nail unitary
construction regulation unit 24 is configured as a unitary
construction with the nail units 24a and 24b at the front side, but
the nail units may be arranged on the left or right, or at the back
end of the cover unit 20 as a unitary construction with the
regulation unit.
[0065] In the present embodiment, an example of arranging both the
nail unitary construction regulation unit 24 and the wall unitary
construction regulation unit 25 is explained above as an example of
a regulation unit, but one of them may be arranged, and none of
them may be arranged. It is preferable that the resin sheet 22 is
positioned in two directions by, for example, touching the two
sides of the resin sheet 22.
[0066] In addition, according to the present embodiment, an example
of the plane part 12 formed on the same plane is explained as an
example of a contact surface which contacts the sealing member 23.
However, automatically it is preferable that the contact surface is
a plane, a surface which is not a complete plane is also
acceptable. For example, a curved surface may be acceptable.
[0067] Furthermore, according to the present embodiment, the
battery storage unit 11 is described as an example of a waterproof
area, but the cover unit 20 may be provided in a waterproof area
other than the battery storage unit 11.
[0068] In the above-mentioned embodiment, the cover unit 20
includes the sealing member 23, and the regulation units 24 through
27. The sealing member 23 contacts the plane part (contact surface)
12 formed on the same surface of the body unit 10 all along the
periphery of the battery storage unit (waterproof area) 11, thereby
sealing the battery storage unit 11. The regulation units 24
through 27 regulate the position of the sealing member 23.
[0069] Therefore, the mobile telephone 1 may be downsized by
suppressing the increase in dimension in the direction of the width
of the wall etc. of the mobile telephone 1 which occurs when, for
example, the sealing member 23 is pressed in the direction of the
width of the mobile telephone 1. Furthermore, since the regulation
units 24 through 27 regulates the position of the sealing member 23
which is arranged in a limited space, a displacement, a
deformation, etc. which occurs when the sealing member 23 is
arranged may be prevented, thereby reserving the cut-off
function.
[0070] Therefore, according to the present embodiment, the mobile
telephone 1 may be downsized with the cut-off performance
maintained.
[0071] Furthermore, according to the present embodiment, the
sealing member 23 and the regulation units 24 through 27 are
arranged on the cover unit 20 side, not on the body unit 10 side.
Therefore, the sealing member 23 may be easily arranged on the
mobile telephone 1, the cut-off performance may be improved, and
the sealing member 23 as a consumable unit may be easily
replaced.
[0072] Furthermore, according to the present embodiment, the cover
unit 20 includes a nail units 24a and 24b which are engaged in the
body unit 10, and the regulation surface 24d (nail unitary
construction regulation unit 24) is provided as a unitary
construction with the nail units 24a and 24b. Therefore, the
position of the sealing member 23 may be regulated with a simple
configuration, thereby further downsizing the mobile telephone
1.
[0073] In addition, according to the present embodiment, as
illustrated in FIGS. 9 and 10, the nail unitary construction
regulation units 24-1 and 24-2 (regulation surfaces 24-1d and
24-2d) and the nail units 24-1a and 24-2a are provided as a unitary
construction with the convex part which projects from the cover
unit 20 with rectangular section one of whose four sides is open.
The regulation units 24-1 and 24-2 (regulation surfaces 24-1d and
24-2d) regulate the position of the sealing member 23 at the end
parts 24-1d and 24-2d on the apertures 24-1e and 24-2e sides of the
convex part. Furthermore, the nail units 24-1a and 24-2a are
provided at the end part on the close side opposite the end parts
24-1d and 24-2d on the open sides. Therefore, the position of the
sealing member 23 may be more correctly regulated with a simple
configuration.
[0074] Furthermore, according to the present embodiment, the cover
unit 20 includes the two nail units 24a and 24b which are engaged
in the body unit 10 and the coupling unit 24c which is provided as
a unitary construction with the two nail units 24a and 24b and
couples the two nail units 24a and 24b. In addition, the nail
unitary construction regulation unit 24 (regulation surface 24d) is
provided as a unitary construction with the two nail units 24a and
24b and the coupling unit 24c. Therefore, the position of the
sealing member 23 may be more correctly regulated with a simple
configuration.
[0075] According to the present embodiment, the wall unitary
construction regulation unit 25 is provided as a unitary
construction with the left wall 21a so that the unit projects from
the left wall (wall surface) 21a provided around the cover unit 20.
Therefore, a simple configuration may be realized, thereby further
downsizing the mobile telephone 1.
[0076] According to the present embodiment, as illustrated in FIGS.
2 and 5, the wall unitary construction regulation unit 25 projects
from the left wall 21a so that the open side end part 25a having a
rectangular section one of whose four sides is open faces the left
wall 21a. Furthermore, the wall unitary construction regulation
unit 25 regulates the position of the sealing member 23 at the
close side end part 25b opposite the open side end part 25a.
Therefore, while suppressing the sink which occurs on the wall
surface during the formation when the close part faces the wall
surface, the position of the sealing member 23 may be
regulated.
[0077] Furthermore, according to the present embodiment, as
illustrated in FIG. 6, the wall unitary construction regulation
unit 25-1 projects from the left wall 21a so that one open side end
part 25-1a as one side of the H-shaped section faces the left wall
21a, and regulates the position of the sealing member 23 at another
open side end part 25-1b. Therefore, while suppressing the sink
which occurs on the wall surface, the position of the sealing
member 23 may be more correctly regulated.
[0078] In addition, as illustrated in FIG. 17, when the left wall
(wall surface) 21a provided around the cover unit 20 functions as a
regulation unit, the position of the sealing member 23 may be
regulated with a simple configuration.
[0079] Furthermore, according to the present embodiment, the cover
unit 20 includes a resin sheet 22 with the sealing member 23 formed
on the surface. Therefore, the sealing member 23 may be simply
arranged more correctly. Additionally, as compared with a metal
plate, a lightweight configuration may be designed with the wave
etc. for charging the battery 30 prevented from being cut off.
Furthermore, as compared with the case in which the cover body 21
and the resin sheet 22 are designed as having a double cover
structure, the attaching operation of the cover unit 20 may be more
easily performed.
[0080] In addition, according to the present embodiment, the cover
unit 20 regulates the position of the sealing member 23 by touching
the resin sheet 22. Therefore, the position of the sealing member
23 may be more correctly regulated.
[0081] Furthermore, as illustrated in FIGS. 4 and 18, when the
resin sheet 22-1 is formed in frame form all along the periphery of
the battery storage unit 11, the cover unit 20 includes a plurality
of regulation units 26 which touch the inner periphery surface
22-1a of the resin sheet 22-1, thereby more correctly regulating
the position of the sealing member 23. Additionally, using the
resin sheet 22-1 in frame form, the distance between the battery 30
and the cover body 21 may be shortened, thereby especially
downsizing the mobile telephone 1 in the direction of the thickness
of the battery.
[0082] Furthermore, the cover unit 20 may include a plurality of
regulation units 26 which touch the inner periphery surface 22-1a
of the resin sheet 22-1 in frame form, and a plurality of
regulation units 27 which touch the outer periphery surface 22-1b
of the resin sheet 22, thereby more correctly regulating the
position of the sealing member 23.
[0083] In addition, according to the present embodiment, since the
waterproof area is the battery storage unit 11, the above-mentioned
cover unit (waterproof cover) 20 may downsize the mobile telephone
1, and reserving the cut-off performance of the battery storage
unit 11.
